Dry shade gardening

Asked March 20, 2017, 11:13 PM EDT

There are two big evergreen trees (Douglas Fir?) and a mature Silver maple tree in my front yard. Under those trees, the grass has hard time to grow, especially with evergreen trees dropping a lot of "needles" on the grass. I want to get rid of the grass and make a flower and shrub garden. Since the trees are on the north side of yard, there aren't much light in that area. I would like to know what perennials, small shrubs (deciduous or/and evergreen) and ornamental grass are suitable growing in this dry shade area. Thanks Joy
